OptionPricer v.4.0 will value puts and calls on stocks which pay or do not pay dividends. The binomial algorithm used accounts for discrete dividends correctly, as opposed to a continuous dividend approximation using the Black Scholes formula.
This new version incorporates several major changes, including the following:
• New algorithm which is much more efficient.
• Completely re-segmented the application to make more efficient use of memory.
• Although the application uses very little memory, safety procedures have been installed to prevent a system crash due to insufficient memory.
• More immediate input checking saves time.
• In version 4.0, any blank input will be read as an error. A zero must be entered if a value is zero. While this may be more tedious, it is less ambiguous than in the previous version.
• A potential bug existed in v3.01 -- if a string too large was entered in the input dialog, a stringrange error crash could ensue. This bug has been eliminated.
• New scrollable help dialog added. (Much thanks to J P Wind.)
• Changed Window type on input dialog box to allow switching via Multifinder.
• Special Keys on extended keyboard now work on both the input (Escape = Cancel) and Help dialogs (Page Up, Page Down, Home, End). In addition, Help can now also be accessed via the «Help» Key.
• Numerous assorted aesthetic improvements to interface.
